AB vs SFTBY: Which Is the Better Buy in 2026?

Same yardstick, side by side (as of October 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. AB and SFTBY share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined AB and SFTBY exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker. Walnut is not an investment adviser.

SoftBank Group Corp. is a Japanese strategic investment holding company led by founder Masayoshi Son. Its main assets are a roughly 90% stake in chip designer Arm Holdings, a stake of about 13% in OpenAI (built from cumulative commitments of roughly $64.6 billion by October 2026), a large holding in Japanese telecom SoftBank Corp., and the Vision Fund portfolios, which hold stakes in companies such as Coupang, DiDi and Klarna along with a ByteDance position. Over 2025 and 2026 it sold holdings including Nvidia and T-Mobile US to fund its AI commitments, took a stake in Intel, and backed the Stargate data center build-out with OpenAI and Oracle, with Son named chairman of that venture. It has also announced a planned Ohio power and data center campus that a SoftBank executive described as having about 10 gigawatts of planned capacity. In practice, the group has moved from a diversified venture investor toward a concentrated, debt-funded vehicle for AI infrastructure and model companies.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• AB drivers: Assets under management scale; Distribution-driven income.
• SFTBY drivers: OpenAI valuation and a possible IPO; Arm Holdings.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: AB's revenue is tightly linked to markets, so a downturn in equities or bonds would shrink the fee base and the distribution alongside it. For SFTBY, concentration is the core risk: a large share of NAV now rests on two assets, one of them private and valued at funding-round prices that could be marked down.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick AB if you believe its drivers more; SFTBY if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the AB and SFTBY guides.

AB. AB trades at a modest earnings multiple (roughly 10x trailing and 9x forward) that reflects its status as a mature, market-sensitive asset manager rather than a growth stock. The standout feature is the distribution yield near 10%, a function of the MLP pass-through structure that returns almost all cash to unitholders each quarter. With the payout ratio near 100% and units down about 10% in 2026, both the yield and the multiple should be read against the risk that markets or flows turn negative; the seven covering analysts have a consensus hold and a mean target near $37.

SFTBY. SoftBank is usually valued on NAV minus a discount rather than on earnings, because profits are dominated by mark-to-market gains and losses on its holdings. The company reported NAV per share near ¥12,700 at June 30, 2026 against a Tokyo price near ¥6,000, though press estimates of NAV were lower by August as listed holdings fell, so the discount moves with both the assets and the share price. The 4-for-1 share split effective January 1, 2026 restated all per-share figures. The dividend is small relative to the share price (a post-split forecast of ¥11 per share for the full year to March 2027), so returns for holders have come almost entirely from price changes rather than income.

Headline figures (approximate, October 2026): AB shows assets under management ~$900B (preliminary, September 30, 2026), operating partnership revenue (q2 2026) ~$888M (2025 full year ~$3.5B), q2 2026 adjusted epu ~$0.82 vs ~$0.83 consensus, distributions (ttm) ~$3.47/unit, ~10% yield; SFTBY shows net asset value (june 30, 2026) ~¥72 trillion (company figure; ~¥58 trillion in early-August press estimates), loan-to-value ratio ~13% (policy ceiling 25%), q1 fy2026 net income (apr to jun 2026) ~¥347 billion, down ~18% year on year, vision fund gain, fy to march 2026 ~$46 billion, mostly OpenAI.

AB and SFTBY are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined AB and SFTBY exposure against your real portfolio. It is not an investment adviser.
